Definitions

  • My present invention relates to processes for-sterilizing milk or similar liquids by continuously passing the liquid through a heated tube system or.the like under pressure.
  • the object of my invention is to reduce the consumption of heat, for instance, steam, and also to reduce' the consumption of cold in the case of usin after the heating tube system a cooling tu e system or the like in which the sterilized milk is being cooled down to about ordinary temperature in order to be filled in transport cans or the like.
  • the invention consists chiefly in. enabling the hot milk under pressure to boil by passing it through a chamber of lower pressure that is ordinary air pressure, and allowing the milk va ours thus developed to be condensed in tlie milk passing to the heating system.
  • the bottom of the chamber 6 is connected with the feeding tube of the pump 3 through a tube 8 provided with a float valve or the like 9 by means of which a suitable milk level is maintained in the chamber 6.
  • a tube 10 leads to the cooler 11 and therefrom through a valve or cock 12 to one or more canning places or the likenot shown on the drawing.
  • valve or cook 12 If the valve or cook 12 is closed, or if the milk quantity circulated by the pump 3 exceeds the milk quantity being canned, the nnlk level will rise When the milk level is sufficiently high the float valve 9 is opened and the milk is returned by the tube 8 to the pump so as to circulate again through the heatlng'system.
  • the necessary pressure for passing the milk through the cooler and the canning devlces or the like may be obtained by arranging the chamber 6 as an upper or overhead cistern so that the tube 4 connectin it with the heating system, is a rising tu e, while the tube 10 connecting it with the cooler, is a dro tube.
  • the heating s stem an if desired also the cooler, may e arranged in the same hei ht as the evaporating chamber and the may be arranged after the cooler.
  • the pressure valve 5 may be arrangedat a suitable point of the tu behind the heating system.
  • One or more check valves 13 in the feeding conduit prevent back flow of the milk.
  • the float valve or the like 9 may be regulated in such a manner that the a ove mentioned closed circulation of the milk through the heatingsystem takes place to such an extent that normally only one third to one sixth of the milk quantity circulated through the heating system passes to the cooler.
  • the resent plant When working in this manner that is by repeatedly passing the liquid through the heating system the resent plant may be used for the production of condensed milk or the like, the tube 7 being in this case omitted so that the milk vapours are not condensed in the fresh or circulating milk rop tube 4, if desired directly,
